Abstract

The study of turbine blade profile performance by using 3-Dimensional CFD is very important because it determining the quality of turbine to produce the power output.Basically,there are two methods when study the turbines blade profile performance,first is by doing the experimental method and second is by using simulation software such as CFD.In this study,using 3- Dimensional CFD simulation method is chosen,since this method is cheaper and save more time compare to experimental method.The geometry used for this analysis are NACA 84 12,NACA 8413 and NACA 8414 that are referring to airfoil geometry.All the selected turbines blade profiles are conduct the analysis with the same parameter.The parameters are used for the turbine ' blade analysis are velocity inlet of 265 m/s,angle of attack of 0 degrees, temperature of 11 12 K and twist angle of 36 degrees. After conduct the simulation,the result is compare to determine wruch turbines blade has the best performance. Hence,the performance of turbine is evaluating based on the coefficient of lift,coefficient of drag,lift and drag coefficient,velocity streamline and also pressure contour.As result of simulation obtain,NACA 8414 is chosen to have the best turbines blade profile performance since give good result for all the coefficient of lift,coefficient of drag,lift and drag coefficient,velocity streamline and also pressure contour.
